Automated verification of distributed programs is a challenging problem. Since the behavior of a distributed program encompasses the behavior of the network, possible configurations of the network have to be investigated during verification. This leads to very large state spaces, and automated verification becomes infeasible. We present a framework that addresses this problem by decoupling the behavior of distributed programs from the behavior of the network. Our framework is based on a set of stub classes that replace native methods used in network communication and enables verification of distributed Java applications by isolating their behavior from the network. The framework supports two modes of verification: unit verification and integration verification. Integration verification checks multiple interacting distributed application components by running them in a single JVM and simulating the behavior of the network within the same JVM via stub classes. Unit verification targets a single component of a distributed application and requires that the user write an event generator class that utilizes the API exported by the framework. While unit verification only checks a single application component, it benefits from a greatly reduced state space compared do that of integration verification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
